The median arcuate ligament is a ligament under the diaphragm that connects the right and left crura of diaphragm.
Structure
The median arcuate ligament is formed by the right and left crura of the diaphragm.{{cite journal | vauthors = Bayat I, Wang J, Ho P, Bird D | title = Intravascular ultrasound-guided laparoscopic division of the median arcuate ligament | journal = Journal of Vascular Surgery Cases and Innovative Techniques | volume = 6 | issue = 1 | pages = 147–151 | date = March 2020 | pmid = 32154471 | pmc = 7056607 | doi = 10.1016/j.jvscit.2020.01.011 }} The crura connect to form an arch, behind which is the aortic hiatus, through which pass the aorta, the azygos vein, and the thoracic duct.

In between 10% and 24% of people, the median arcuate ligament occurs very low.{{Cite journal|last1=Surrusco|first1=Matthew S.|last2=Michelotti|first2=Marcos J.|last3=Garberoglio|first3=Carlos A.|last4=Mukherjee|first4=Kaushik|date=2018-07-27|title=A Novel Approach to Median Arcuate Ligament Release Using Robot-Assisted Surgical Techniques and Intraoperative Indocyanine Green Angiography|url=https://www.liebertpub.com/doi/10.1089/vor.2018.0540|journal=Videoscopy|volume=28|issue=5|doi=10.1089/vor.2018.0540|url-access=subscription}}
Clinical significance
Compression of celiac artery and celiac ganglia by the median arcuate ligament being too low in some individuals;Iqbal, S., & Chaudhary, M. (2021). Median arcuate ligament syndrome (Dunbar syndrome). Cardiovascular Diagnosis And Therapy, 11(5), 1172-1176. doi:10.21037/cdt-20-846 can lead to the median arcuate ligament syndrome, which is characterized by abdominal pain, weight loss, and an epigastric bruit.{{cite journal | vauthors = Duncan AA | title = Median arcuate ligament syndrome | journal = Current Treatment Options in Cardiovascular Medicine | volume = 10 | issue = 2 | pages = 112–6 | date = April 2008 | pmid = 18325313 | doi = 10.1007/s11936-008-0012-2 | s2cid = 1606510 | url = http://www.treatment-options.com/1092-8464/10/112 | url-status = dead | archive-url = https://web.archive.org/web/20121204073128/http://treatment-options.com/1092-8464/10/112 | archive-date = December 4, 2012 | url-access = subscription }}
